Since the former is made to hold and hold the adapter with the clamp piece for hollow support, when the cold cathode fluorescent lamp vibrates or the like, the connection with the cold cathode fluorescent lamp may become unstable.

On the other hand, since the clamp piece is adapted to hold the adapter on the mounting portion, the connection with the cold cathode fluorescent lamp is more stable than the former, but in order to hollow support the cold cathode fluorescent lamp, A pedestal is required separately.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a contact and a connection device capable of stably connecting and supporting electronic components such as cold cathode fluorescent lamps in a hollow manner.

In order to solve the above problems, a contact of the present invention is a contact to which an electronic component is connected, which is formed on a base portion, a base portion, a support portion capable of supporting a lead terminal of the electronic component, and located on both sides of the support portion on the base portion. And at least two clamp portions each of which is capable of sandwiching lead terminals of the electronic component between the supporting portions.

In the case of such a contact, since the support part and the clamp part are formed on the base part, the lead terminal of the electronic component is supported in the hollow by the support part and held by the clamp part and the support part. Therefore, the contact can stably connect and support the electronic component in a hollow manner.

The base portion is a substantially U-shaped plate in plan view or a substantially O-shape in plan view. The base portion is continuous to the first plate portion and to both end portions of the first plate portion, and faces in the same direction. It is preferable that it is a shape which has two 2nd board part bent. In this case, the support portion is a plate body formed at the upper end of the first plate portion and bent in the same direction as the second plate portion, and the clamp portion is a plate body formed upward at the upper end of the second plate portion, respectively.

In this case, when the lead terminal of the electronic component is inserted between the clamp portions, the lead terminal is held between the clamp portion and the support portion. For this reason, the mounting and dismounting of the lead terminals becomes very simple. Further, since the base portion is substantially U-shaped in plan view or approximately 0-shape in plan view, the installation state is stabilized by being installed on an installation portion of an electronic device such as a substrate. For this reason, there is an advantage in stably connecting and supporting the electronic component in a hollow. Moreover, since the said base part, the support part, and the clamp part are plate bodies formed integrally, it can produce easily by press molding etc. Therefore, the cost of the contact can be reduced.

In the case where the contact is a board mounting type, the contact is a plate body formed downward in the lower end of the base part, and a contact part connected to the substrate and a plate body formed downward in the lower part of the base part, and at least one of the engaging parts caught by the substrate. In addition, it can be set as the structure provided. In this case, the lower end face of the base portion is in contact with the substrate in at least one of the states where the contact portion is connected to the substrate and the locking portion is caught by the substrate.

In this state, the lower end surface of the base portion is brought into contact with the substrate while the contact portion is connected to the substrate and / or the engaging portion is caught by the substrate. Thus, the contact is stably placed on the substrate at the same time as the contact and / or the engagement of the contact with the substrate. Can be installed as

It is preferable that a contact part is formed in the lower end part of the 1st board part of a base part, and it is preferable that a latching part is formed in the lower end part of the 2nd board part of a base part, respectively, toward downward. In this case, the lower end surface of the base portion is in contact with the substrate in a state where the contact portion is connected to the substrate and the locking portion is caught by the substrate.

In this case, the contact portion is connected to the substrate by solder or the like, and the locking portion is caught by the substrate, so that the base portion is attached to the substrate at at least three points. In this state, since the base portion is stably provided on the substrate, there is an advantage to stably connect and support the electronic component in a hollow.

A first connecting device of the present invention includes an adapter connected to an electronic component having a main body portion and a lead terminal formed at an end of the main body portion in the longitudinal direction thereof, and the contact connected to the electronic component via the adapter. Doing. The adapter is formed between a first connection portion electrically and mechanically connected to a lead terminal of an electronic component, a second connection portion disposed opposite to an end portion of a main body portion of the electronic component, and a first connection portion and a second connection portion. And an elastic deformation portion capable of elastic deformation by thermal expansion or thermal contraction in the longitudinal direction of the electronic component. The support portion of the contact is capable of supporting the second connection portion instead of the lead terminal of the electronic component, and the clamp portion can sandwich the second connection portion between the support portion and not the lead terminal of the electronic component. It is supposed to be done.

In the case of such a first connecting device, the electronic component is thermally expanded in a state where the first connecting portion of the adapter is connected to the lead terminal and the second connecting portion of the adapter is held in the clamp portion and the supporting portion of the contact. Alternatively, when thermally contracted, the elastic deformation portion elastically deforms in the longitudinal direction of the electronic component. As a result, thermal expansion or thermal contraction of the electronic component is absorbed. For this reason, by the thermal expansion or thermal contraction of the electronic component, the load applied to the lead terminal and the main body portion of the electronic component connected to the first connecting portion of the adapter can be reduced.

The clamp portion is curved inwardly and elastically contacts the lead terminal of the electronic component, so that the lead portion can be held between the support portion and the upper end portion of the contact portion and inclined outward. It can be set as the shape which has inclination parts, respectively. In this case, it is preferable that the distance between the upper end portions of the inclined portion is larger than the width dimension of the lead terminal of the electronic component, and the distance between the top portions of the contact portion is smaller than the width dimension.

In this case, when the lead terminal of the electronic component is inserted between the inclined portions, the contact portion is pressed against the lead terminal, the clamp portion is elastically deformed, and is displaced outward. When the lead terminal passes over the contact portion, the clamp portion returns and displaces inward. As a result, the contact portion is brought into contact with the lead terminal, and the lead terminal is held between the support portion. Since the inclined portion, which is the upper end of the clamp portion, is inclined outward and the distance therebetween is larger than the width dimension of the lead terminal, it is possible to prevent a problem such that the lead terminal is damaged by the upper end of the clamp portion during insertion. .

A second connecting device of the present invention includes an adapter connected to an electronic component having a main body portion and a lead terminal formed in the longitudinal direction at an end of the main body portion, and the contact connected to the electronic component via an adapter. have.

Moreover, it has an elastic deformation part which can be elastically deformed by thermal expansion or thermal contraction of the longitudinal direction of an electronic component. The supporting portion of the contact is capable of supporting the second connecting portion instead of the lead terminal of the electronic component. The contact portion of the clamp portion contacts the second connecting portion instead of the lead terminal of the electronic component, thereby providing the second connecting portion. The distance between the upper end portion of the inclined portion is larger than the width dimension of the lead terminal of the electronic component, rather than the width dimension of the second connecting portion, and the distance between the top portion of the contact portion The width of the lead terminal of the electronic component is smaller than that of the second connecting portion.

In the case of such a second connecting device, when the second connecting portion of the adapter is inserted between the inclined portions, the contact portion is pressed against the second connecting portion, the clamp portion is elastically deformed, and is displaced outward. When the second connection portion passes over the contact portion, the clamp portion returns and displaces inwardly. Thereby, a contact part contacts a 2nd connection part and hold | maintains the said 2nd connection part between support parts. Since the inclined portion, which is the upper end of the clamp portion, is inclined outward and the distance therebetween is larger than the width dimension of the second connecting portion, there is a problem that the second connecting portion is damaged by the upper end of the clamp portion during insertion. It can prevent. Further, when the electronic component is thermally expanded or thermally contracted while the first connecting portion of the adapter is connected to the lead terminal and the second connecting portion of the adapter is held in the clamp portion and the supporting portion of the contact, the elastic deformation portion is the electronic component. Is elastically deformed in the longitudinal direction. As a result, thermal expansion or thermal contraction of the electronic component is absorbed. For this reason, by the thermal expansion or thermal contraction of the electronic component, the load applied to the lead terminal and the main body portion of the electronic component connected to the first connecting portion of the adapter can be reduced.

The said contact can also be set as the structure which has the upper part in the upper end part of the 2nd board part of a base part, respectively, and has at least 2 holding part which can pinch the edge part of the main body part of an electronic component.

In this way, by holding the main body of the electronic component in the holding portion, vibration of the electronic component can be suppressed, and a load caused by the vibration is applied to the entire electronic component, or a part of the electronic component collides with the adapter by the vibration. Can be suppressed.

The said holding part can be made into the shape which has the holding part main body curved by the outer side by the external shape of the main body part of an electronic component, and the inclination part which is continuous in the upper end part of this holding part main body, and inclined toward the outer side. In this case, it is preferable that the distance between the upper end portions of the inclined portions is larger than the width dimension of the main body portion of the electronic component, and the distance between the lower end portions of the inclined portions is smaller than the width dimension.

That is, when the main body portion of the electronic component is inserted between the inclined portions of the holding portion, the lower end portion of the inclined portion is pressed against the main body portion, the holding portion is elastically deformed, and is displaced outward. When the main body portion passes over the lower end of the inclined portion, the holding portion returns and displaces inward. Thereby, the holding | maintenance part main body clamps and hold | maintains a main body part. As such, the inclined portion, which is the upper end of the holding portion, is inclined outward and the distance therebetween is larger than the width dimension of the main body portion of the electronic component, thereby preventing a problem such that the main body portion may be damaged by the upper end of the holding portion during insertion. can do.

In this way, one end of the lamp body portion 11 is inserted into the second connection portion 120, so that the second connection portion 120 is disposed opposite the one end portion.

The elastic deformation part 130 is a coil spring part of the said coil spring which is continuous to the edge part of the 2nd connection part 120, and whose coil spacing is coarser than the 2nd connection part 120. FIG. When the elastic force of the elastic deformation portion 130 is stretched, the load is not applied to the sealing portion of the lead terminal 12 of the cold cathode fluorescent lamp 10 and the lead terminal 12 of the lamp body portion 11. It is set by force. In addition, the inner diameter of the elastic deformation portion 130 is approximately equal to the inner diameter of the second connecting portion 120.

Two clamp portions, each of which is supported upward at the upper end portions of the support portion 220 protruded at the upper end portion of the intermediate portion (first plate portion) and the proximal end portion portions of both end portions (second plate portion) of the base portion 210, respectively. 230 and two holding parts 240 protruded upwards at the upper end portions of the tip end side portions at both end portions of the base portion 210, and the lower ends at the lower end portions of the middle portion of the base portion 210, respectively. The contact portion 250 and the lower end portions of both end portions of the base portion 210 are provided with two locking portions 260 extending downwards, respectively.

The base part 210 has the intermediate part which is a substantially rectangular plate body, and the both end part which is continued to the both ends of this intermediate part, and is bent at substantially right angle with respect to the said intermediate part, respectively.

The support part 220 is a substantially L-shaped plate in the horizontal direction when viewed from a side bent at substantially right angles in the same direction as both end portions of the base part 210, and is continuous to the upper end of the middle part of the base part 210. It has a vertical part and a horizontal part continuous to the upper end part of this vertical part and bent substantially perpendicularly with respect to the said vertical part. The horizontal portion is a portion where the second connection portion 120 of the adapter 100 is mounted together with the lamp body portion 11 of the cold cathode fluorescent lamp 10. The length dimension of the horizontal portion is slightly longer than the length dimension of the proximal end portion of both end portions of the base portion 210 and the bent portion 241 of the holding portion 240 on the proximal end portion portion of the both end portions of the base portion 210. It does not interfere with the length.

Each clamp portion 230 is a plate body having a width dimension slightly shorter than the length dimension of the base end side portion of the base portion 210, and includes an extension portion 231 continuous to the upper end of the base end side portion, and the extension portion. It has the contact part 232 continuous to the upper end of 231, and the inclination part 233 continuous to the upper end of the contact part 232. As shown in FIG.

The extension part 231 is a linear plate part continuous to the base end side part of the both ends of the base part 210, and is located in the side of the support part 220. As shown in FIG. The contact portion 232 is a plate portion curved in an inward direction. The inclined portion 233 is a plate portion bent to incline toward the outside.

The distance between the upper end portions of both inclined portions 233 is larger than the diameter (that is, width dimension) of the second connecting portion 120 of the adapter 100. The distance between the top portions of the both side contact portions 232 is smaller than the diameter of the second connection portion 120. For this reason, when the second connection portion 120 is inserted between the inclined portions 233, the contact portions 232 are pressed against the second connection portions 120, respectively, and the clamp portions 230 are elastically deformed, respectively. Displace outward. When the second connection part 120 passes over the contact part 232, the clamp parts 230 return and displace inward. Thereby, the contact part 232 contacts the 2nd connection part 120 at an angle upwards, and it hold | maintains the 2nd connection part 120 between the support part 220 and hold | maintains. In addition, since the distance between the upper end portions of both inclined portions 233 is larger than the diameter of the second connecting portion 120 of the adapter 100, the second connecting portion 120 is disposed between the inclined portions 233. When is inserted, the upper end of the inclined portion 233 does not damage the second connecting portion 120.

Each holding | maintenance part 240 is a plate body, The bending part 241 continuous to the upper end of the said front-end | tip part part of the base part 210, and the holding part main body 242 continuous to the upper end of this bending part 241 is carried out.

The holding portion main body 242 is a plate portion that is curved outward in an arc shape by the outer shape of the lamp body portion 11 of the cold cathode fluorescent lamp 10. The inclined portion 243 is a straight plate portion that is bent to be inclined outward.

The distance between the upper end portions of both inclined portions 243 is larger than the diameter of the lamp body portion 11 (that is, the width dimension), and the distance between the lower end portions of the inclined portions 243 is determined by the ramp body portion 11. It is smaller than the diameter. For this reason, when the lamp main body 11 is inserted between the inclined portions 243, the lower ends of the inclined portions 243 are pressed, respectively, and the holding portions 240 are respectively elastically deformed and displaced outward. When the lamp main body 11 crosses the lower end of the inclined portion 243, the holding portions 240 respectively return and displace inwardly. Thereby, the holding | maintenance part main body 242 clamps and hold | maintains the lamp main-body part 11. In addition, when the distance between the upper end of the inclined portion 243 is larger than the diameter of the lamp main body 11, the inclined portion (2) is inserted when the lamp main body 11 is inserted between the inclined portions 243. The upper end of 243 is not to damage the lamp main body 11.

The contact portion 250 is a straight plate body in which both edge portions of the tip portion are cut off, and is inserted into the through-hole 22 of the substrate 20 and is electrically connected.

Each locking portion 260 has a substantially inverted U-shaped arm portion 261 that can be elastically deformed, and a pair of outwardly convex locking claws respectively formed on both ends of the arm portion 261.

The pair of catching claws 262 are inserted into the catching holes 21 of the substrate 20 and are caught by the lower surfaces of both edge portions in the longitudinal direction of the catching holes 21. As a result, the contact 200 is mounted on the substrate 20.

The length dimension of both front-end | tip parts of the arm part 261 becomes substantially the same as the thickness dimension of the board | substrate 20. As shown in FIG. For this reason, the lower end surface of the base portion 210 is in contact with the substrate 20 in a state where the locking claws 262 are caught by both edge portions of the locking holes 21 of the substrate 20, respectively.

The contact 200 having such a configuration is mounted on the substrate 20 as follows. First, the two locking portions 260 of the contact 200 are inserted while being aligned with the two locking holes 21 of the substrate 20. Then, a pair of catching claws 262 of the catching portions 260 are pressed to the upper ends of both side edge portions of the catching holes 21, respectively, and both front ends of the arm portions 261 of the catching portions 260 are inward. Elastic deformation.

When the pair of catching claws 262 of the catching portion 260 passes over both edge portions of the catching hole 21, both ends of the arm 261 of the catching portion 260 are elastically deformed outward. . As a result, the catching claw 262 is caught by the lower surfaces of both edge portions of the catching hole 21. Then, the bottom surface of the base portion 210 is in contact with the substrate 20. In this way, the contact 200 is mounted on the substrate 20.

At the same time, the contact portion 250 of the contact 200 is inserted into the through hole 22 of the substrate 20. As a result, the contact 200 is electrically connected to the substrate 20.

Hereinafter, the procedure of connecting the adapter 100 to which the cold-cathode fluorescent lamp 10 is connected to the contact 200 mounted on the board | substrate 20 as mentioned above is demonstrated.

First, the lamp main body 11 of the cold cathode fluorescent lamp 10 is connected between the second connecting portion 120 of the adapter 100 between the inclined portions 233 of the two clamp portions 230 of the contact 200. The end of is pressed between the inclined portions 243 of the two holding portions 240 of the contact 200.

Then, the contact portion 232 of the clamp portion 230 is pressed against the second connection portion 120, respectively, the clamp portion 230 is each elastically deformed and displaced outward. When the second connection part 120 passes over the contact part 232, the clamp parts 230 return and displace inward. Thereby, the contact part 232 contacts the 2nd connection part 120 at an angle upwards, and it hold | maintains the 2nd connection part 120 between the support part 220 and hold | maintains.

At the same time, the lower end portions of the inclined portion 243 are pressed against the lamp body portion 11, respectively, and the holding portions 240 are each elastically deformed and displaced outward. When the lamp main body 11 crosses the lower end of the inclined portion 243, the holding portions 240 respectively return and displace inwardly. Thereby, the holding | maintenance part main body 242 clamps and hold | maintains the lamp main-body part 11. In this manner, the cold cathode fluorescent lamp 10 and the adapter 100 are hollowly supported by the contact 200, and the cold cathode fluorescent lamp 10 is electrically connected to the contact 200 via the adapter 100. .

As shown in Fig. 6 (b), when the adapter 100 and the cold cathode fluorescent lamp 10 are connected to the contact 200, the cold cathode fluorescent lamp 10 thermally expands in the longitudinal direction thereof. The elastic deformation portion 130 of the adapter 100 is stretched, and the first connection portion 110 of the adapter 100 is shown in the longitudinal direction together with the lead terminal 12 of the cold cathode fluorescent lamp 10. Move to the right.

On the other hand, as shown in Fig. 6C, when the cold cathode fluorescent lamp 10 is thermally contracted in the longitudinal direction, the elastic deformation portion 130 of the adapter 100 contracts and the first of the adapter 100 is contracted. The connecting portion 110 moves together with the lead terminal 12 of the cold cathode fluorescent lamp 10 to the left shown in the longitudinal direction.

At this time, since the second connecting portion 120 of the adapter 100 is held in the two clamp portions 230 of the contact 200, the thermal expansion of the lamp body portion 11 of the cold cathode fluorescent lamp 10 or It does not move in the longitudinal direction by heat shrink.

In this manner, thermal expansion or thermal contraction of the cold cathode fluorescent lamp 10 is absorbed by the elastic deformation of the elastic deformation portion 130 of the adapter 100.

Hereinafter, a procedure of separating the cold cathode fluorescent lamp 10 and the adapter 100 from the contact 200 will be described. First, the cold cathode fluorescent lamp 10 is lifted upward. Then, the contact portion 232 of the clamp portion 230 is pressed to the second connection portion 120 of the adapter 100, respectively, the clamp portion 230 is each elastically deformed and displaced outward. Then, when the 2nd connection part 120 passes over the contact part 232, the 2nd connection part 120 can be pulled out between the inclination parts 233 of the clamp part 230. As shown in FIG. Thereafter, the clamp portions 230 each return and displace inwardly.

At the same time, the upper end of the holding body 242 of the contact 200 is pressed against the lamp body 11 of the cold cathode fluorescent lamp 10, respectively, and the holding portions 240 are elastically deformed and displaced outward. . When the lamp main body 11 crosses the upper end of the holder main body 242, the lamp main body 11 can be pulled out between the inclined portions 243 of the holder 240. Thereafter, the holding portions 240 return and displace inwards, respectively. In this manner, the cold cathode fluorescent lamp 10 and the adapter 100 can be easily separated from the contact 200.

In the case of such a connection device, when the bottom surface of the base portion 210 having a substantially U shape is in contact with the substrate 20 when viewed from the plane of the contact 200, it is stably installed on the substrate 20. The second connecting portion 120 of the adapter 100 is held together with the cold cathode fluorescent lamp 10 by the support portion 220 and the clamp portion 230 formed at the upper end of the base portion 210. For this reason, the contact 200 of the connection device can stably maintain the cold cathode fluorescent lamp 10 in a hollow manner. In addition, since the lamp main body 11 of the cold cathode fluorescent lamp 10 is held by the holding part 240 of the contact 200, vibration of the lamp main body 11 and the like can be suppressed. For this reason, it is possible to suppress that the load caused by the vibration is applied to the entire cold cathode fluorescent lamp 10 or that a part of the cold cathode fluorescent lamp 10 is collided with the adapter by the vibration.

In addition, since the contact 200 is a press-molded product, it can be manufactured at low cost. Therefore, there is an advantage in reducing the cost.

In addition, the adapter 100 allows the cold cathode fluorescent lamp 10 to absorb thermal expansion or thermal contraction by elastic deformation of the elastic deformation unit 130. For this reason, the end portion and the lead terminal 12 of the lamp body portion 11 of the cold cathode fluorescent lamp 10 are pressed by the adapter 100 held in the contact 200 by thermal expansion or thermal contraction, or Since the separation from the adapter 100 can be prevented, the load on the cold cathode fluorescent lamp 10 can be reduced during the thermal expansion or thermal contraction.

In addition, the said connection apparatus can be arbitrarily changed as long as it is suitable for the meaning of a claim. It will be described in detail below. Fig. 7 is a diagram illustrating a first design change example of the adapter, Fig. 7 (a) is a side view, Fig. 7 (b) is a perspective view of a state connected to a cold cathode fluorescent lamp, and Fig. 8 is a second view of the adapter. 8 (a) is a perspective view, FIG. 8 (b) is a side view of a state connected to a cold cathode fluorescent lamp, and FIG. 9 (a) is a third design change of the adapter. A perspective view illustrating an example, FIG. 9 (b) is a perspective view illustrating a fourth design change example of an adapter, and FIG. 10 is a perspective view illustrating a first design change example of a contact, in which an adapter and a cold cathode fluorescent lamp are connected. Fig. 11 is a perspective view illustrating a second example of design change of a contact, Fig. 11 (a) seen from the front upper side, and Fig. 11 (b) seen from the back upper side.

The said adapter is formed between the 1st connection part electrically and mechanically connected to the lead terminal of an electronic component, the 2nd connection part arrange | positioned facing the edge part of the main body part of an electronic component, and the 1st, 2nd connection part. It can be arbitrarily changed if it is provided with the elastic deformation part which can be elastically deformed by thermal expansion or thermal contraction of the electronic component in the longitudinal direction.

For example, as shown in Fig. 7, the adapter may have a coil spring type different from the above embodiment in which the first connecting portion is a cylindrical coil body, and the elastic deformation portion is a conical coil body. As shown in the drawing, it may be of a type composed of a metal plate having press-formed conductivity.

The latter adapter includes a first connecting portion having an approximately L-shaped cross section and having an insertion hole in which the lead terminal is inserted in the center thereof, a second connecting portion curved in a cylindrical shape so as to face each other with a distal end face, and The elastic deformation part formed between 1st and 2nd connection parts is provided. The elastic deformation portion has first, second and third base plates and deformation portions. The first base portion is formed continuously at the end of the intermediate portion of the second connecting portion. The 2nd, 3rd base part is arrange | positioned at intervals between the said 1st base part and the base end part of a 1st connection part. The first deformable portion has a pair of U-shaped members each formed between both end portions of the first and second base portions. The second deformable portion has a pair of U-shaped members each formed between both end portions of the second and third base portions. The third deformable portion has a pair of U-shaped members each formed between the third base portion and the base end portion of the first connecting portion. Each U-shaped member is curved in a semi-circular arc shape, and elastically deformable in the direction in which these two end portions approach each other or in the direction away from each other. That is, the elastic deformation of each U-shaped member absorbs thermal expansion or thermal contraction of the electronic component. In addition, as for the said adapter, a skirt part is formed in the rear end of the said 2nd connection part, as shown to FIG. 9 (a), or a some flange part is shown as FIG. 9 (b), or It is also possible.

The contact is a contact to which an electronic component is connected, which is formed on a base portion, a support portion formed on the base portion, and capable of supporting the lead terminals of the electronic component, and positioned on both sides of the support portion on the base portion, respectively. If at least two clamp parts which can pinch the lead terminal of an electronic component are provided between the parts, design can be changed arbitrarily.

As long as the holding portion and the at least two clamp portions are formed, the base portion may be subjected to any design change. For example, as shown in FIG. 10, the base portion is a substantially O-shaped plate when viewed in plan, from the first plate body to which the holding portion is extended and from both end portions of the first plate body in the same direction. It is also possible to have a configuration including two second plates that are bent and the clamp portion is extended upward, and two third plates that are bent so that their front end faces face each other from the ends of the second plates. As described above, even if the base portion is a planar body having an approximately O shape, it can be stably installed on the substrate.

In addition, the said base part is not limited only to a plate body. For example, the base portion may be a resin pedestal or the like. Moreover, the said base part can also use this part as said support part. Moreover, although it is preferable that the lower surface of the said base part can be made to contact on a board | substrate in the state in which the said contact part connected to the board | substrate, and / or the latching part caught on the board | substrate, it is not limited to this.

Although the said support part is said to support the 2nd connection part of the said adapter, it is not limited to this, It is possible to set it as the structure which supports the lead terminal of electronic components, such as a cold cathode fluorescent lamp.

It is possible to arbitrarily change the clamp portion as long as it is a structure capable of sandwiching a lead terminal of an electronic component such as a second connection portion of the adapter or a cold cathode fluorescent lamp between the support portion. For example, the said clamp part can be made into the arc-shaped board body which convexed outward. Moreover, in the said Example, although said clamp part was said to be two, it may be more than that. For example, the three clamp portions may be arranged in a zigzag shape, and the second connecting portion or the lead terminal may be held between the supporting portions.

Whether or not to form the holding portion is arbitrary. That is, as shown in FIG. 10 and FIG. 11, it can abbreviate | omit. Moreover, as long as it is a shape which can hold | maintain the main-body part of an electronic component, the said holding | maintenance part can change design arbitrarily. For example, you may make the said holding part the same shape as the clamp part 230, and hold | maintain the main part of the electronic component supported with the 2nd connection part of an adapter to the said support part.

Whether to form the said contact part also is arbitrary. That is, the base portion may be directly connected to a substrate or the like, or a signal line may be connected to the base portion and connected to a substrate or the like through the signal line. Moreover, about the shape of a contact part, as long as it can be connected to a board | substrate, it can change design arbitrarily. For example, as shown in FIG. 10, the said contact part is a board body bent at substantially right angle with respect to the both ends of a base part, and can be set as the shape connected to the pattern on a board | substrate. In addition, the contact portion can be electrically and mechanically connected to the substrate by soldering or the like, so that the contact portion can function as a mounting means on the substrate.

It is arbitrary whether or not to form the locking portion as well. The shape of the locking portion can be arbitrarily changed if possible. Therefore, the locking portion described herein includes not only the male side of the locking claw, but also the female side of the locking hole or the locking groove that hangs the locking projection formed on the substrate or the like.

 In the above embodiment, the electronic component is referred to as a cold cathode fluorescent lamp, but is not limited thereto. The body part and the lead terminal of the electronic component are not limited to the columnar shape. In addition, about the shape and arrangement | positioning of each part, if the function similar to the said Example is realizable, it can change arbitrarily.
